TIP: Face Unlock lets you unlock
your phone by looking at the
screen. After you set it up, look under
Settings > Personal > Security
for two additional settings: Improve
face matching and Liveness check.
Use these to make Face Unlock
more reliable and secure.
• Pattern lets you draw a simple pattern
with your finger to unlock the phone. This
is slightly more secure than Face Unlock.
• PIN requires four or more numbers. Longer
PINs tend to be more secure.
• Password requires four or more letters or
numbers. This is the most secure option,
as long as you create a strong password.
Password tips: For best security, specify a
password that is
• A least 8 characters long.
• Contains a mixture of numbers, letters,
and special symbols.
